These macro's make it easier to specify (interval) times\-:


\begin{DoxyCode}
\textcolor{preprocessor}{ #define  S * ( 1000 * 1000 )}
\textcolor{preprocessor}{}\textcolor{preprocessor}{ #define MS * 1000}
\textcolor{preprocessor}{ #define US * 1}
\end{DoxyCode}


Time in the \hyperlink{class_r_t_o_s}{R\-T\-O\-S} is expressed in microseconds. Using these marco's avoids knowledge of this detail.
